Tornado vs asyncio: What are the differences?

Introduction

In this article, we will explore the key differences between Tornado and asyncio, two popular frameworks used for asynchronous programming in Python.

Execution Model: Tornado is an event-driven framework, while asyncio is based on coroutines. Tornado uses an event loop to manage events and callbacks, allowing it to handle a large number of simultaneous connections efficiently. On the other hand, asyncio employs coroutines, which are lightweight functions that can be paused and resumed, to achieve asynchronous execution.
Compatibility: Tornado is compatible with both Python 2 and Python 3, making it suitable for a wider range of projects. asyncio, on the other hand, is specifically designed for Python 3.4 and above, taking advantage of the language improvements introduced in later versions.
Code Structure: Tornado follows a more traditional approach with explicit callbacks and the use of decorator-based syntax for defining request handlers. It provides a comprehensive set of features for building web applications, including routing, template rendering, and WebSocket support. asyncio, on the other hand, provides a more lightweight and flexible framework for asynchronous programming, allowing developers to create custom event loops and use coroutines in a more modular manner.
Community and Support: Tornado has been around for a longer time and has a larger community of users and contributors. It has been extensively used in production environments and has a well-documented API. asyncio, being a relatively newer framework, is still evolving and may have fewer third-party libraries and resources available.
Concurrency Models: Tornado uses a single-threaded, non-blocking I/O approach to achieve high concurrency. It achieves this by using asynchronous networking and non-blocking file I/O operations. asyncio, on the other hand, provides a more granular control over concurrency through the use of coroutines and can handle more complex concurrency patterns, such as concurrent HTTP requests.

In summary, the key differences between Tornado and asyncio lie in their execution models, compatibility, code structure, community support, and concurrency models. These differences make them suitable for different types of projects and use cases.

Advice on Tornado, asyncio

Needs advice

I want to use Redis non-blocking with Tornado. How I should use the Redis code using tornadis to achieve max number of connections. I had used the tornadis and with WebSocket handler, I inherited the Redis based pub/sub client inside a class and in the main loop we created the instance of a class. but it decreases the numbr of connections with a huge amount. how we should configure?

Detailed Comparison

Tornado	asyncio
By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.	This module provides infrastructure for writing single-threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related primitives.

What are some alternatives to Tornado, asyncio?

Node.js

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Rails

Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.

Django

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

Laravel

It is a web application framework with expressive, elegant syntax. It attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as authentication, routing, sessions, and caching.

.NET

.NET is a general purpose development platform. With .NET, you can use multiple languages, editors, and libraries to build native applications for web, mobile, desktop, gaming, and IoT for Windows, macOS, Linux, Android, and more.

ASP.NET Core

A free and open-source web framework, and higher performance than ASP.NET, developed by Microsoft and the community. It is a modular framework that runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core.

ExpressJS

Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications.

Symfony

It is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP..

Spring

A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.

Spring Boot

Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
